On Friday, the school leader came to the class and said, "Go to the multimedia classroom next Monday. Everyone will bring a deck of playing cards and a piece of A4 white paper. The principal will attend classes. "

As soon as the bell rang, the school leaders sat in their seats and listened carefully to the teacher. The teacher said how many cards were in a deck of playing cards; There are several colors; There are several colors; How many pieces of each color are there; We cooperated with the teacher to answer all these basic questions.

The teacher went on to say that 52 cards (except Wang and Da) represent 52 weeks in a year, four colors represent four seasons, one color has 13 cards, and the sum of points of 13 cards is 9 1 day, which means that a season is 9 1 day. After the teacher finished, he asked us questions, and the students scrambled to answer the teacher. The school leaders were very happy to see us listening carefully and applauded all the time.

This is a very interesting math class, which let me know the hidden secrets in playing cards.
